Black screen caps lock key blinks

Laptop screen is blank and the caps lock key blinks 3 times over and over..Tried doing what was suggested, taking out and reinstalling the memory card..also blew out the dust and didn't fix the problem ..I think it's Windows 7 installed.

Hi there @Philvasquez
Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.
I am sorry to here that you are getting this particular error code and that your initial troubleshooting has not helped.
I assume that you were looking through this page, and followed it.
Computer does not start and the LEDs blink or the computer beeps
LEDs blink 3 times
Memory
Module error not functional
If you have followed the process within that page, related to a memory problem, and it is still doing the same thing, then you are looking at two possibilities. One or more of the memory modules in your notebook is defective, or the main board has a faulty connection.
You can try testing the memory individually or by swapping them (if there are two) into the different memory sockets. Doing this you can isolate if one memory chip or the other is defective, or if it is a socket problem.
Once you know which problem it is , you will likely need to get replacement memory, or a replacement board, or in a worst case both.
See the following, for more details on the compatible parts and type of memory that are supported.

Hp G62-a70SV Black Screen, Caps lock not blinking

Hello,
My hp G62-a70SV gives me a black screen when I push the power button.
Caps lock isn't blinking at all, wifi led is on.
Nothing is ever displayed on screen. I hear eventually the windows starting, but nothing more.
I connect external monitor, but there is no signal.
Is it problem of the display adapter on the system board?

Hi,
It's always worth trying a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.

quick succession then there is about a second delay then
it keeps repeating the same pattern,also the number

I have a HP Probook 4535s (now out of warranty)
When I turn it on it freezes at the Hp start up screen
It does`nt matter which "F" key I press after a few
seconds it starts to beep (not in the identifying a
problem way) This includes the "Esc" key
Whatever key I have pressed it goes from just
text to having a white box around the text
but does nothing
I have reseated the RAM and them replaced

is maller than the original all with the
same results, so am at a loss.

Oh sorry I have also removed the battery and held
down the power button to purge it
Thank you in advance for reading my post
Best regards
Neil
ps I have not got the recovery disks (lost when we moved)

Sorry to hear that. Please refer to the Blank Screen LED Error Codes document from HP Support. It sounds like a "General system board failure." The explanation says to contact HP for assistance. The motherboard might need to be replaced, and you will probably require the assistance of a technician to fix the problem.

HT1338 Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.

Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.
This blinking occurs when no keyboarding is going on.
Back-up is not running.
I am on-line.

Anthony:
The normal practice is to use the Shift key when typing a single Capital letter, as in a name or the beginning of a sentence, and the Caps Lock key to type all caps. The easiest thing would be for you to retrain your little finger to use the Shift instead of Caps Lock. I know of no way to display an icon at the bottom of the monitor to display that the caps lock key is engaged.

My laptop won't turn on when I push the power button, just light on the caps lock key blinking

my laptop hp mini 311-1002TU suddenly hang, and can't to respon anyting from user, then I shut it down by force by pressing the power button, but when I tried to turn it on again, my laptop does not turn on, just the lights in his caps lock blinking, please help to resolve this problem, thanks.

I would suggest keep trying to turn it on and get the blue screen error code to maybe a get clue of precisely what the issue is. Ultimately, the processor likely needs to be replaced in most of these 1-blink situations.
If you have experience taking a laptop apart, here is a link to the Maintenance and Service Guide for your model. Removal and replacement procedures begin in Section 4.
Otherwise, I would recommend taking it to a local repair shop because they may have processors and/or other parts that they can swap in and out to determine if the processor is actually bad or not.

HP Dv6z-7200 Notebook blinking caps lock key, red wifi button

I re-did the thermal paste on my computer (Dv6z-7200, AMD A10-4600m, Radeon 7670m, 6Gb RAM ) and i put it back together, and the screen does not come on, the power button lights up, the wifi key is red and then the caps lock key blinks indefinetly, and the fan comes on. Lucky for me my buddy has the same laptop so I took out the motherboard on mine and put it in his' with his' hard drive, RAM, wlan, etc. and it still didn't work. So it must be the motherboard, right? Could it be something with the BIOS? If it is the motherboard that is fried, could someone direct me to where i can get a new one? I tried the hp part surfer website, but could not find it. Thank you -Zach

Hi Nayj424,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your Compaq Presario CQ62-102TX Notebook and getting a blank or black screen on startup. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to turn on the computer you start to press F11 repeatedly till the menu opens. You can do a system restore.
Hope this is helpful.
Thanks.

Hello SuperMario1,
Thanks for your response.
The last thing i did, remove CMOS battery and after a few minutes i plugged it.
Then connect AC power adapter and press power button.
Laptop starts but gives a error message
"The CMOS checksum is invalid, The BIOS will be reset to the default configuration and will be rebooted."
Finally laptop start normally. It works fine ...
But same problem when i restart
"blank screen caps lock blink 2 times every 3/4 sec"
So finally
1. remove CMOS battery and after a few minutes i plugged it again
2. connect AC power adapter and press power button
3. laptops starts normally (with a error msg same as previous)
4. Upgrade bios to F.29(previously i had F.24)
5. Everythings works fine (restart/shutdown have no effect)

Blinking caps lock key

Anybody know why my caps lock key has started blinking. It isn't blinking fast and I thought I was seeing things at first but it is flashing now and then.

If you were talking about an Atari ST I would say 100% keyboard fault, the keyboard on the ST is 'intelligent' and this is the way it tells you it gone faulty - maybe similar thing going on with yours ?

Problem that starts with *apparent* sticking caps lock key

I have a mid-2009 MacBook Pro (two weeks outside of AppleCare, of course!). Last night, it appeared the caps lock key was sticking. It would type in all caps even when I hit the button and the green indicator light went off. Moments later, I noticed that the option that shows you all the windows on the same screen was suddenly going very, very slow. I tried to restart but it started in safe mode - twice. It finally started correctly on the third or fourth reboot. I hoped it was a fluke.
Unfortunately it's happening again and rebooting doesn't seem to fix it - I can't put in my password to login because it thinks I'm typing in all caps.
Any ideas, please? Thanks.

This may enter the Apple Hall of Fame for stupid posts. I spent a couple hours last night restarting the computer, trying restore etc....and really doing anything I could from clinton's link in order to identify the problem. I'd even called our local store to let them know I would be there first thing in the morning (I'm boarding a plane in a few minutes and really needed my laptop for this trip).
So after doing all of those things + removing the caps lock key to see if it was somehow manually stuck, I go the store this morning. Virtual panic. I needed a presentation off the laptop for a workshop tomorrow and I hadn't backed up since I created it...
I enter the store, I begin to explain the situation in detail, I open up the laptop....
And the guy at the store says "Did you notice your shift key is stuck down?". Why No, I hadn't noticed that! With a tiny wiggle and a tap, that key popped back into place and the computer worked fine. The Safe Mode was happening because the shift key was down.

Screen problems - black screen and lock-up (plus HDMI issues)

Hi, I'm not sure if these are related to the same fundamental issue, but they are both serious problems that need resolution.
I have a new mid-2012 MBPretina. I am on all the latest updates (10.8.2).
The first problem is the most recent, and the most serious problem. Since I updated the Java a couple of days ago I've been experiencing random black screens and lock-ups. Essentially, what happens is that sometimes when I perform an action (opening an app, clicking a link on a webpage, performing other kinds of in-app actions, etc.) the computer screen will go black. About half the time I can, through my own memory, try keyboard combinations to quit or force quit the most recently used app (the one where the action was just performed), and I will get some glimpse of the underlying apps, while the menubar and other areas will remain black until I move a window on top of the black space. Sometimes no key combinations work and I am forced to perform a hard restart with the power button. This is a serious issue, obviously, since I will lose current work/progress in my apps. I'm not sure if this is because of the new Java update, or has to do with something else, but it started happening shortly thereafter, over the last 2 days. I work most of my waking day on my laptop, and this "black screen of death" has happened about 5 or 6 times a day.
The second problem I have been experiencing since I starting using my MBPr with external HDMI displays in August/September. The problem is that I will plug the MBPr into an HDMI display, the screen will temporaliy go black, and then bring me to the login screen (as if it's crashing, albeit softly). This happens about 1 out of 4 times nowadays.
How can I fix these problems, especially the first?

UPDATE:
Clearly there's a problem because a third of the way through a clean reinstallation from scratch it black screened again. Hmmmm.
Now this is not good. Problem is I can't rule out potential updates from Apple that might have caused this either.
The search for solutions continues.

No display while caps lock LED blinks

Hi
Please could someone help me.
For about 2 weeks now my laptop has refused to display anything. When I turn it on, nothing displays on the screen but the caps lock LED blinks once every 2 seconds. Also the wireless button displays orange light but nothing on the screen.
It managed to display once in this 2 weeks and the error message I was able to see before it came on read something like:
HP Battery Alert
The system has detected the storage capacity of .....(did not see all the message on this line)
very low. For optimal performance, this battery .... (did not see all the message on this line also)
Primary(internal) Battery (601)
